This Week’s Sky: January 23rd-29th

Monday, January 23rd: Venus shines bright

Venus shines bright at a magnitude -4.7 in the sky about a half-hour after sunset.  Currently, it is the brightest object in the night sky, shining 10 times brighter than Jupiter, the second object with the highest magnitude. Look in the southwest sky between Aquarius and Pisces, where Venus can be seen until around 9:00 p.m. local time.


Tuesday, January 24th: Moon, Saturn, Mercury

The waning crescent Moon is low in the southeast sky.  Find Saturn to the upper right of the Moon and Mercury about 6 degrees below the Moon.


Wednesday, January 25th: Sirius and Betelgeuse

Sirius shines below Orion in the southeast sky.  At 8 p.m. (depending on your location) Sirius will shine directly below Betelgeuse in Orion’s shoulder.


Thursday, January 26th: Ganymede crossing Jupiter

Jupiter’s moon Ganymede is also the largest satellite in the Solar System.  It will cross Jupiter’s northern polar region, transiting from 2:55 a.m. to 5:02 a.m. EST.


Friday, January 27th: New Moon

There is a New Moon at exactly 7:07 p.m. EST.


Saturday, January 28th: Orion Nebula

With the New Moon, the weekend will be free of moonlight. The darker sky creates a wonderful opportunity to see the brilliant Orion Nebula located in the Sword of Orion.


Sunday, January 29th: Tiny Crescent Moon

Even though the New Moon occurred on Friday, a sliver of the Crescent Moon can be seen in the low southwest sky after sunset.  It is approximately 4 percent lit.
